P Supervisory Circuits
The MAX707/708 are costeffective system supervisor circuits
designed to monitor V
CC
in digital systems and provide a reset signal
to the host processor when necessary. No external components are
required.
The reset output is driven active within 20 sec of V
CC
falling
through the reset voltage threshold. Reset is maintained with 200 mS
of delay time after V
CC
rise above the reset threshold. The
MAX707/708 have a low quiescent current of 12
an activehigh RESET and activelow RESET with a pushpull
output. The output is guaranteed valid down to V
CC
= 1.0 V. The
MAX707/708 have a Manual Reset MR input and a +1.25 V threshold
detector for powerfail input PFI. These devices are available in a
Micro8 and SOIC8 package.
